Apache Axis2/C Version 1.5.0

ASF Releases Apache Axis2/C Version 1.5.0

Apache Software Foundation. July 21, 2008.

Apache Software Foundation developers announced the release of Apache Axis2/C Version 1.5.0.

Apache Axis (1.X) is an implementation of the Simple Object Access Protocol (SOAP); Apache Axis2 is a redesign of Axis (1.X) supporting SOAP 1.2/SOAP1.2/REST/and more.


Apache Axis2/C is a Web services engine implemented in the C programming language. It is based on the extensible and flexible Axis2 architecture. Apache Axis2/C can be used to provide and consume WebServices. It has been implemented with portability and ability to embed in mind, hence could be used as a Web services enabler in other software.

Apache Axis2/C supports SOAP 1.1 and SOAP 1.2, as well as REST style of Webservices. A single service could be exposed both as a SOAP style as well as a REST style service simultaneously. It also has built in MTOM support, that can be used to exchange binary data.

Apache Axis2/C is efficient, modular and is designed with extensibility. The extensible design allows it to support the full WS-* stack with the concept of modules. Apache Axis2/C is the Web services engine that supports the most number of WS-* specification implementations in C, with guaranteed interoperability. This enables using C in Service Oriented Architecture (SOA) implementations, and would be very useful when integrating legacy systems into SOA.

The following WS-* specifications are supported, either as built in modules or as separate Apache projects:

  1. WS-Addressing: Built in to Axis2/C
  2. WS-Policy: Built in to Axis2/C
  3. WS-Security: Implemented by Apache Rampart/C project
  4. WS-SecurityPolicy: Built in to Axis2/C
  5. WS-ReliableMessaging: Implemented by Apache Sandesha2/Cproject
  6. WS-Eventing: Implemented by Apache Savan/Cproject

Apache Axis2/C Version 1.5.0 Key Features

  1. Support for one-way messaging (In-Only) and request response messaging (In-Out)
  2. Client APIs: Easy to use service client API and more advanced operation client API
  3. Transports supported: HTTP
    • Inbuilt HTTP server called simple axis server
    • Apache2 httpd module called mod_axis2 for server side
    • IIS module for server side. Support IIS 5.1, 6 and 7
    • Client transport with ability to enable SSL support
    • Basic HTTP Authentication
    • libcurl based client transport
    • AMQP Transport support using Apache Qpid
  4. Module architecture, mechanism to extend the SOAP processing model
  5. WS-Addressing support, both the submission (2004/08) and final (2005/08) versions, implemented as a module
  6. MTOM/XOP support
  7. AXIOM, an XML object model optimized for SOAP 1.1/1.2 messages; This has complete XML infoset support
  8. XML parser abstraction
    • Libxml2 wrapper
    • Guththila pull parser support
  9. Both directory based and archive based deployment models for deploying services and modules
  10. Description hierarchy providing access to static data of Axis2/C runtime (configuration, service groups, services, operations and messages)
  11. Context hierarchy providing access to dynamic Axis2/C runtime information (corresponding contexts to map to each level of description hierarchy)
  12. Message receiver abstraction
    • Inbuilt raw XML message receiver
  13. Code generation tool for stub and skeleton generation for a given WSDL (based on Java tool)
    • Axis Data Binding (ADB) support
  14. Transport proxy support
  15. REST support (more POX like) using both HTTP POST and GET
  16. Comprehensive documentation
    • Axis2/C Manual
  17. WS-Policy implementation called Neethi/C, with WS-SecurityPolicy extension
  18. TCP Transport, for both client and server side

Changes Since Last Release

  1. AMQP Transport support with Apache Qpid
  2. Modifications to IIS Module to support IIS 6 and 7
  3. Added a JScript file to automate IIS module registry configuration
  4. Improved the in-only message handling
  5. Specifying the MEP in the services.xml for non in-out messages made mandatory
  6. Improvements to Guthtila for better performance
  7. Improvements to TCPMon tool
  8. Memory leak fixes
  9. Bug fixes
